示例1: Texture
public Texture(Sdx.Bitmap bmp)
{
// Variables
Sdx.Imaging.BitmapData bmpdata= bmp.LockBits(new Sdx.Rectangle(0, 0, bmp.Width, bmp.Height), Sdx.Imaging.ImageLockMode.ReadOnly, Sdx.Imaging.PixelFormat.Format32bppArgb);
int tid= GL.GenTexture();
GL.BindTexture(TextureTarget.Texture2D, tid);
GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgba, bmp.Width, bmp.Height, 0, PixelFormat.Bgra, PixelType.UnsignedByte, bmpdata.Scan0);
bmp.UnlockBits(bmpdata);
GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMinFilter, (int) TextureMinFilter.Linear);
GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMagFilter, (int) TextureMagFilter.Linear);

}示例2: SetImageDataToRawImg
private static void SetImageDataToRawImg(sdr.Bitmap png, RawImgClass p3img)
{
sdr.Imaging.BitmapData bmpData;
p3img.imgData = new byte[(int)(p3img.Width * p3img.Height * ((float)p3img.BitCount / 8))];
bmpData = png.LockBits(new sdr.Rectangle(0, 0, png.Width, png.Height), sdr.Imaging.ImageLockMode.ReadOnly, png.PixelFormat);
sirs.Marshal.Copy(bmpData.Scan0, p3img.imgData, 0, p3img.imgData.Length);
png.UnlockBits(bmpData);

/// <param name="dev">XNAのGraphicsDevice</param>
/// <param name="bmp">Bitmap形式の元画像</param>
/// <returns>Texture2D形式の画像</returns>
